To all whom it may concern.-

Be it known that I, WILLIAM C. Rrcnsnn- 80H, a citizen of the United States, residing at Mystic, count of No a London, and State of Connecticut, ave invented certain new and useful Improvements in Door-Mats, of which the followin is a specification, reference being had to 516 drawings accompanyin the same. V

y invention relates to a door-mat composed of a series of moving brushes'arranged and adapted to automatically remove the dirt from the shoes or boots of ersons as they walk upon said series of move le brushes.

The objects of my invention are to provide means located near the entrance of a building whereby the boots or shoes of persons walking upon the device will be automatically cleaned of the refuse of the street to prevent its being tracked into the halls and corridors of the building.

Another object of my device is to so construct a door-mat that the brushes thereon will be cleaned of the dirt removed from the boots and shoes and deposited in a rece tacle underneath same, where it can be readi y disinfected and removed.

In the drawings accompanying this specification, Figure 1 is an isometric plan view of my device as applied to and secured in the floor of a buildin vice with a portion of the brushes removed. Fig. 3 is a sectional elevation through line 3 3 of Fig.2. Fig. 4 is a sectional elevation through line 4 4 of Fig. 2. Fig. 5 is a sectional elevation through line 5 5 of Fi 2. Fig. 6 is an end elevation of one set of bru hes, showing the shafts and sprockets upon which they are mounted, together with one of the set of cleaning-brushes. Fig. 7 is a view similar to that shown in Fig. 6, showing another set of cleaning-brushes. Fig. 8 is a sectional view of a modified form of my device.

In the drawin s illustrating my invention, 1 represents the rams or casing, to which my device is attached, said casin 1 havin bearings in its side walls, in whic the sha 2 2 have a bearing. Upon said shafts 2 2 are mounted the treads 3 3. The treads 4 4 are made thicker in order to furnish hearings for the shafts '5 5'. Mounted on shafts 5 5 are the sprocket-wheels 6 6, which guide and move the sections 7 7 7, &c., of the brushes.

Fig. 2 is a plan of my de- It will be noted in 6 and 7 that the first,

third, fifth, &c., of t e series of brushes 7 7 revolve in one direction and the remainin of the series in the opposite direction; e right hand of said sprockets '6, as shown in Fig. 6, 1S keyed to the shaft 5. The other of said sprockets shown in said figure is loose upon said shaft, so that it may revolve thereon. In Fig. 7 is shown the next brush to that of Fig. 6, in which the left-hand s rocket 6 is secured tothe shaft 5, the ot er of said sprockets 6 being loose thereon. U n the s aft 8 is mounts a; series of cleaningrushes 10, secured thereto in such manner that they revolve therewith, the brush 10 being so placed that the bristles contact with the series of brushes 7 underneath the framework in order to clear the brushes 7 7 &c., of any dirt lodged thereon in the operation of cleaning boots or shoes. The shaft 9 has mounted thereon the brush 1 l, rotating in an opposite direction from the series of brushes 10, which series of'brushes 11 clean the brushes F, mov ing in an opposite direction from the series shown in Flg. 6.

12 is an upright provided with hearings in which are mounted the shafts 8 and 9 in such manner as to freely revolve therein.

13 represents an electric motor or other suitable means for moving the brushes 7 7, &c., and for revolving the cleaning-brushes 10 and 11. In case an electric motor is used a belt, as 14, runs over a pulley on said m0- tor and over a sleeve 25 on one of the shafts 2, which sleeve has two other pulleys formed thereon, and the gear 26, which meshes with the gear 27 to drive the brushes 7 The belt 15 runs from one of said pulleys to a pulley 28, mounted on one of the shafts 5, to drive one of the series of brushes 7. Another belt 16 runs from one of the .ulleys 25 to a pulley 29, secured to the shat 9, to revolve same and to revolve the shaft 9 through the medium of the gears i7 and 18, secured upon said shafts 9' and S.

19 19 represent se ments of a ear which is a part of the tree 5 4 4, whic se ments have teeth thereon adapted to enmes with the gears 20 20. Said gears 20 20 are mounted upon the shaft 21. Said shaft 21 has a hearing at each of its ends in the frame 1. The shaft 21 is revolved by means of the bevel-gears 23, through the medium of the shaft 24, which has a square end thereon too ada ted to receive a wrench. The purpose of t e segments 19 and the gears 20 s to revolve the whole framework sup ortmg the brushes around the'bearin 30 0 one of the shafts 2 to swing it upwar ly in order to get into the bottom of the framework 2 to clean out the dirt accumulated there or to enable repairs or adjustment to be made to the different portions of the mechanism. 7

31 31 31 represent hand-rails so placed that persons. coming into the entrance of a buildmg will be obhged to walk upon the moving brushes in order that their shoes may be cleaned.

The operation of my device is as follows: The door-mat is designed to be laced in front of the entrance oor of a bu iding and the rails 31 31 set in such position that ersons entering at the door will be oblige to walk across the moving brushes. The brushes may all be moved in one direction or the first in one direction and the second in the other direction, and so on. A person walking across the brush steps upon and is borne up by the treads 3 3, above which the bristles of the brush project slightly, as is shown in Fig. 3, above the treads in order to reach the hollow of the foot and the ed es of the soles of a boot or shoe. The sai movable brushes and the cleaning-brushes may be revolved or operated through any suitable source of power, such as a steam-englne, water-motor, electric motor, &c. the source of power not being a part of my invention.

Having claim isdescribed my invention, what I 5 IKA door-mat, comprising a series of flat brushes pivoted end to end to form an endless belt; means for moving said brushes par allel to the surface of supports for supportin the feet of a erson walking upon sai brushes; and sai supports. ,7 5

2. A door-mat comprising a series of endless chains having brush-surfaces on their outer faces; means for moving said brushes; means for supporting the feet of a erson walking u' on said brushes and means or automatical y cleaning said brushes.

3. A door-mat com rising a series of endi less chains having flat rush-surfaces on'th'eir outer faces; means for supporting and movmy hand, in t e presence of two subscribing wltnesses, this the 24th da of March, 1905.
